Just my opinions: Try to avoid getting into rote learning. I learned that way as a kid, I'll find myself writing squiggly notes just because somehow it makes me remember stuff the act of writing something. For coding stuff I don't really have notes about "coding" more on random neat tricks/concepts(like about Git/Systemd), which means store them somewhere eg. an app that has a global search like OneNote/Evernote/Notes(Mac). For general fast learning I recommend crash courses on YouTube eg. by Traversy Media/others. Also using sandboxes where some code is already setup so you can have something to work from. Generally though I think practice is what will make it stick and personal desire to achieve/build something that you want.
